Product details
Overview
R5F101GFANA#U0 from Renesas is a 48-pin HWQFN-packaged 16-bit RL78/G13 microcontroller with 128 KB flash, 8 KB data flash, and 12 KB RAM, operating from 1.6 V to 5.5 V at up to 32 MHz (41 DMIPS), optimized for ultra-low-power industrial control applications including sensor nodes and battery-powered HMI.
For engineers reviewing the R5F101GFANA#U0 datasheet, R5F101GFANA#U0 pinout, R5F101GFANA#U0 application, or R5F101GFANA#U0 equivalent, key selection criteria include its 0.57 μA STOP mode current, integrated RTC + LVD, 26-channel 10-bit ADC, and hardware UART/SPI/I²C interfaces supporting LIN-bus and background data flash rewriting.
Technical Context
The R5F101GFANA#U0 implements the RL78 CPU core with 3-stage pipeline CISC architecture, supporting instruction execution times from 0.03125 μs (32 MHz high-speed mode) to 30.5 μs (32.768 kHz subsystem clock). It integrates a 12-bit interval timer, real-time clock with calendar/alarm/correction, and watchdog timer driven by dedicated low-speed on-chip oscillator.
Power management includes HALT, STOP, and SNOOZE modes; voltage detection offers 14-level LVD with selectable interrupt/reset; DMA controller provides 4 channels with 2-clock transfers between SFR and RAM; and the on-chip high-accuracy ±1.0% oscillator supports 1–32 MHz frequencies across full VDD (1.8–5.5 V) and temperature (−40 to +105°C) ranges.
